Answers
Answer:
A. Segment AB congruent segment CD
C. Segment AD congruent segment BC
Step-by-step explanation:
These are both true because a characteristic of a rhombus is that all four sides are congruent. Therefore we must prove that AB is congruent to CD and AD is congruent to BC.

300 = 12i+36si = 10Yes it's reasonablei = -11Refer to the diagram below.
The explanation for each part is below as well.
========================================================
Part 1
i = number of individual nail polish bottles
s = number of sets of 4
12i = money earned from just selling the individual bottles only
36s = money earned from just selling the sets of 4 only
12i+36s = total money earned = 300
12i+36s = 300 is the equation to set up
This is the same as 300 = 12i+36s because A = B is the same as B = A.
========================================================
Part 2
Plug in s = 5 to represent she sold 5 sets. Let's solve for i
12i+36s = 300
12i+36(5) = 300
12i+180 = 300
12i = 300-180
12i = 120
i = 120/12
i = 10
If she wants to sell $300 worth of product overall, and she already sold 5 sets so far, then she needs to sell 10 individual bottles to reach this monthly goal.
========================================================
Part 3
Yes it's reasonable to reach this goal. This is because the value of i (from part 2) was some positive whole number.
========================================================
Part 4
We'll repeat part 2 but with s = 12
12i+36s = 300
12i+36(12) = 300
12i+432 = 300
12i = 300-432
12i = -132
i = -132/12
i = -11
As the instructions state, we get a negative value. This is not reasonable because we can't sell a negative number of items. A negative number of items in general doesn't make sense.
The instructions further state that $432 was already made and that she exceeded her goal. Meaning that she doesn't have to worry about selling the individual bottles if selling the sets has her reach something over $300.

Answers
Answer:
36.87°
Step-by-step explanation:
Given the right angle triangle :
To obtain the value of Cosθ ; we use the trigonometric relation :
Cosθ = Adjacent / Hypotenus
The adjacent angle isn't given :
Opposite = 9 ; hypotenus = 15
Adjacent = √(hypotenus ² + opposite ²)
Adjacent = √(15² - 9²)
Adjacent = √(225 -81)
Adjacent = √144 = 12
Hence,
Cos θ = 12/15
θ = Cos^-1(12/15)
θ = 36.87°

Step-by-step explanation:
0.10x + 0.15(50 - x) = 0.12(50)

0.10x + (7.5 - 0.15x) = 6

A cylinder-shaped sculpture is 24 meters high with a diameter of 6.8 meters. An artist plans to paint the entire surface blue. If one can of paint covers 50 square meters, how many cans does the artist need to paint the sculpture
Answers
Answer:
11.70cans ≈ 12cans
Step-by-step explanation:
According to question,
Given,A cylinder-shaped sculpture is 24 meters high with a diameter of 6.8 meters . thus Radius is 6.8/2 = 3.4 meters .And, An artist plans to paint the entire surface blue. & one can of paint covers 50 square meters.Now,First we have to find the total surface area of cylinder
total surface area of cylinder=2×π×r² + 2×π×r×h
Put values,we get
⇒2×3.14×3.4² + 2×3.14×3.4×24
⇒585.0448 square meters
Now,one can of paint covers 50 square meters.
So,To paint 585.0448 m² Area We need 585.0448 / 50 = 11.70Cans
Total Cans needed is 11.70cans ≈ 12cans .

There was no van stated in the question, but if the van was the truck, the answer would be $50.
Step-by-step explanation:
We can split the problem into 2 parts. First, there is a flat fee of $30 to rent the truck.
Now, we can calculate the cost to rent the truck for 80 miles excluding the flat fee by multiplying the values together.
$0.25/mile * 80 miles = $20
Now, we can add the values up.
This will give us: $30 + $20 = $50
What is the value of k?

Answer:

Step-by-step explanation:
Top angle of tri:
180 - 115 =
65
So:
65+4K+5+6k+10 = 180 (angles in tri add to 180)
Solve:
80+10k = 180
10k = 100
K = 10
Answer:
10
Step-by-step explanation:
y = 180 - 115
y = 65
Total of angles in a triangle is 180
(4k + 5) + (6k + 10) + 65 = 180
combine like terms
10k + 80 = 180
Subtract 80 from both sides
10k = 100
Divide both sides by 10
k = 10
Find the equation of a line that is parallel to y = x + 1 and passes through the point (3,-4).
Give your answer in the form y = mx + b.
Answers
Given:
The equation of a line is:
[tex]y=x+1[/tex]
A line is parallel to the given line and passes through the point (3,-4).
To find:
The equation of the line in the slope intercept form.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept of the line.
We have,
[tex]y=x+1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=1[/tex]
Slope of the given line is 1.
We know that the slopes of parallel lines are equal. So, the slope of the required line is 1.
The required line passes through the point (3,-4) with slope 1. So, the equation of the required line is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(-4)=1(x-3)[/tex]
[tex]y+4=x-3[/tex]
Subtracting 4 from both sides, we get
[tex]y=x-3-4[/tex]
[tex]y=x-7[/tex]
Therefore, the equation of the required line is [tex]y=x-7[/tex].
While she was on holiday,Olga measured the temperature at the same time every day. Here are the results. Work out the median: The range of the temperatures
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required data are not given.
I will use the following data as an illustration of how to calculate median and range.
We have:
[tex]x: 11, 13, 14, 15, 18, 20[/tex]
Calculate range
Identify the highest and the least
[tex]Highest = 20[/tex]
[tex]Least = 11[/tex]
So, the range is:
[tex]Range = Highest -Least[/tex]
[tex]Range =20-11[/tex]
[tex]Range =9[/tex]
Calculate the median
The number of data we are using is 6 (i.e. even).
So, the position of the median item is:
[tex]Median =\frac{1}{2}(n+1)[/tex]
[tex]Median =\frac{1}{2}(6+1)[/tex]
[tex]Median =\frac{1}{2}*7[/tex]
[tex]Median =3.5th[/tex]
A decimal result implies that the median is the mean of the integer values before and after the result.
In this case, the median is the mean of the item at 3rd and 4th positions.
So:
[tex]Median = \frac{14+15}{2}[/tex]
[tex]Median = \frac{29}{2}[/tex]
[tex]Median = 14.5[/tex]

What is the image point of (0,1) after the transformation D4 R90?
Please and thank you
Answers
Answer:
Image point → (-4, 0)
Step-by-step explanation:
Coordinate of a point → (0, 1)
Rule for the transformation has been given as,
D₄ o R₉₀
First use R₉₀ → Rotation of the point by 90° counterclockwise
Rule for the rotation of a point (x, y) by 90° counterclockwise about the origin,
(x, y) → (-y, x)
(0, 1) → (-1, 0)
Further use D₄ → Dilation of the point by a scale factor of 4 about the origin
If a point (x, y) is dilated by a scale factor 'k' about the origin rule for the dilation is,
(x, y) → (kx, ky)
By applying this rule,
(-1, 0) → (-4, 0)
Therefore, image point will be → (-4, 0)

The line L has equation 3y = 4 - 2x
Is line L parallel to AB?
Show your working clearly.
Answers
Answer:
line L is not parallel to AB
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 4 - 2x ( divide terms by 3 )
y = [tex]\frac{4}{3}[/tex] - [tex]\frac{2}{3}[/tex] x ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Calculate slope of AB using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(1, 3) and (x₂, y₂ ) = B(- 2, - 1)
[tex]m_{AB}[/tex] = [tex]\frac{-1-3}{-2-1}[/tex] = [tex]\frac{-4}{-3}[/tex] = [tex]\frac{4}{3}[/tex]
